BED FOR THE SICK.

To all whom it may concera'.

Be it known that I, RUDoLrII Rona, a subject of the King of Norway, anda resident of Kragero, Norway, have invented a new and Improved Bed. forthe Sick, of which the following is a full, clear, and exactdescription.

This invention is an improvement in beds for the sick, especiallyadapted for hospitals and other places where the sick are housed.

Among other objects of the invention is the provision of a sanitaryb'ed, comfortable to the patient and in which the latter may be easilymoved to an inclined or upright position and need not be removed fromthe bed during the period of defecation.

The invention, generally stated, consists of a spring mattress composedof two parts hingedly connected together, and a hair or other cushionmattress superposed thereon, having afunnel-shaped opening substantiallyat its center passing also through the spring mattress. This opening iscovered with canvas, thin rubber or other impervious material, passinwithin a short distance of a receptacle slic able in guides under thebed. A cover intermediate the opening and receptacle is also slidable inguides thereover, acting to close the receptacle when not in use.

Suitable means are provided to move one of the sections of the springmattress on its hinges to carry the body of the patientto the requiredelevation.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the preferred form of my improved bed;Fig. 2 is an outside, fragmentary elevation of the headboard, disclosingthe means operable to raise one of the mattress sections; Fig. 3 is aplan view of the bed; Fig. 4 is a longitudinal, vertical, sectional viewof the same, substantially on the line 44 of Fig. 3 Fig. 5 is asectional View on the line 55 of Fig. 3; Fig. 6 is a sectional viewsubstantially on the line 66 of Fig. 2, disclosing a pawl and ratchetemployed in holding the movable hinged section of the mattress at therequired elevation, and Fig. 7 is a sectional view showing amodification of the means for elevating said hinged section of themattress.

1 indicates a bed frame of any desired construction, on which issupported a spring mattress 2, composed of two sections hinged togetherat 3, the shorter section being Specification of Letters Patent.

placed at the head of the bed and movable to any desired position ofinclination, by the following or other equivalent means: Journaled inbearings 4 at the outside of the headboard of the bed is a transverseshaft 5, each of its ends being squared, making the shaft operable fromeither side of the bed by a removable crank 6. Near each end of theshaft 5 is fixed a pulley 7, having fixed there to a belt 8 passing overa roller 5) journaled in an opening in the head-board, as best shown inFig. 2. The belts 8 after passing over the rollers 9, are directeddownwardly at the inner face of the head-board, thereafter passing underthe short, pivotal section of the spring mattress to which they areconnected. A ratchet-wheel 10 is fixed to the shaft 5 between thepulleys 7 and is normally engaged by the end of a pawl 11 pivoted at 12between suitable ears fastened to the head-board. A spring 13 at alltimes forces the pawl into engagement with the teeth of theratchet-wheel. It is obvious from this construction that on turning theshaft 5 by the crank 6 to wind up the bolts 8 on the pulleys 7, thepivotal section of the mattress at the head of the bed will be drawnupwardly to an inclined position and the pawl 11 will act to sustain itin this position until disengaged from the ratchet-wheel 10.

On the spring mattress 2 is superposed a hair or other cushion mattress14 having a funnel-shaped opening substantially at its center, saidopening also passing through the spring mattress. This opening is linedwith canvas, thin rubber or other impervious material 15, which isrernovably attached at its upper edges to a covering 16 of like materialfastened by buttons 17 to the top of the hair mattress. The covering 16may be unbuttoned and drawn about the patient when in use and therebyavoid pollution of the mattress to which it is normally buttoned.

Secured to the bed frame at each side of the opening in the twomattresses, are stopped guide-ways 18, in which are slidably mounted areceptacle 19 and a cover 20 therefor, the cover being normally arrangedover the receptacle and provided with a handle 21 for withdrawing andreplacing it, and the receptacle having a handle 22 for a like purpose.The guidc-ways 18 are joined to gethcr at their rear ends by a crosspiece 23 of like construction, acting as a stop for the cover andreceptacle when they are in position directly under the lining of theopenings in the mattresses. An upholstered plug 24, as shown in Fig. 4,is shaped to exactly fit the funnel-shaped openings in the mattressesand cork them up when not in use. This plug, as also the cover 20, is tobe withdrawn during the period of defecation.

For cleansing the bed, especially the lining in the opening in themattresses, as also the patient, I employ a tank fixed near the bed andcontaining a disinfectant which is ejected through a tube or hose 26connected therewith.

In Fig. 7 I have shown a somewhat modified means for elevating one ofthe pivotal sections of the mattress, consisting of one or more segmentgears 27 fixed to said section, in mesh with a pinion 28 fixed to ashaft 29 j ournaled in the legs of the bed. The pawl and ratchetmechanism can also be employed in this construction to hold the hingesection of the mattress at the required elevation, as is obvious.

The precise embodiment of the invention is not material provided theessential characteristics are employed as pointed out in the annexedclaim.

Having thus described my invention I claim as new and desire to secureby Letters Patent:

An invalid bed, comprising a bed frame, a spring mattress on the bedframe and formed of hinged sections, means for raising and holding oneof the sections of the mattress in an inclined position, a cushionmattress on the spring mattress, the mattresses having alined openings,stepped guideways secured to the bed frame at opposite sides of theopenings of the mattresses, a receptacle sliding in the lower guideway,and a cover sliding in the upper guideway, the receptacle and coverbeing provided with handles.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
